.Be it knoirn thttt I, FRANCK yll'nnlnnimN, ot' Newport, Cainphellfcounty, Kentuclgyfhve .invented a new and useful Self-Closing DoorHinge and I do hereh'ydeclere the following tobea. fu'll, cl'er, end-exuctdescrip tion thereof, reference being had tothe accompanying drawings, making part of thisspecification'.

. My invention relates toa. device for hanging or lhinging a door, ,which enttbles it-to `close nutomatically and accurately after'bcing opened. My invention-also enables the same door, by a slightfreadjustrnent, to auto* maticzilly swing,r to thexopen position after closure.

The cheeks Il :ind I enclose n tongue7 K, -on thc back ot' the (loor,rso that whcncrer the latter is opened in either direetion,it presses against and pushes buck one or another cheek, and in so (loing winds' the spring H or II-IQes the ense moy he, which spring, the instant that the door is left et liberty, operates to restore `thclctter toits original-position. A Stull, L, projecting from the bottom ot' the door h y falling into the notch c, tc'tsto bring and hold the (loer accurately to its closcdipostion, so that two folding-doors will stond, ivhenshut, precisely flush wit'h each other, or in ucomnion plane. It will he perceived that the' door Alcan be easily lifted out of vits sockets for 'cleaning' or otherwise or by inserting it in :t qunrter-rountlin the sockets, itA will, when liberated, assume the opeminstcnd of the closed position. Instead of being square, the aperture in the eye Gmayhave a. circular form-With a. catch for a. feather on the pintlc, or any other form that will liole'tlie` lut-ter stationary while the door is being operated.,
